The remote NTP server is affected by a denial of service
The remote NTP server is affected by a denial of service vulnerability
due to improper validation of mrulist queries. An unauthenticated,
remote attacker can exploit this, via a specially crafted NTP mrulist
query packet, to terminate the ntpd process.
Note that the NTP server is reportedly affected by additional
vulnerabilities as well; however, Nessus has not tested for these.
